Depending on who's work you were reading last summer Grigo was either a major piece or another throw-in for the Ryan O'Reilly trade. As it turns out he was the one component that had a lasting effect on the 2016 Avs roster. After 3 years of baffling misuse by the Sabres organization, the 12th pick in the 2012 draft returned to his old coach from the QMJHL and began the process of true NHL development.
Prior to joining the Avs, Grigorenko bounced around the NHL, AHL & QMJHL for 3 years with the net result of a wasted ELC totaling 68 games in the NHL and 6 goals & 8 assists to show for it.
